Question about 1996 Saab 900
Yesterday I was driving my Saab. I stopped at a few stores. It died as I was pulling into the parking spot at the last store. I thought that maybe I had pulled off the clutch a bit too soon. I started it back up and pulled the rest of the way into the parking spot. When I cam back to the car and tried to start it up, I couldn't get it to start. The car would crank, but would not start. The radio and everything else electric would work fine. I have checked all the fuses, but wasn't exactly sure how to get to the relays to check them.
Any help on this matter would be greatly appreciated.
In order of failure rate you should check:
1) DIC (the red module sitting between the cam banks). This may or may not throw a code (random misfire or a specific cylinder misfire). The easiest way to check this is to simply swap in a known good DIC and see if this fixes the problem. You should also check your plugs at this point and ensure that they are gapped no larger than 1 mm, as overgapped plugs are the primary cause of DIC filures..
2) CPS (crankshaft position sensor) located on the right front lower corner of the engine block. This should throw a code, but may not. I do not have access currently to the electrical specs you should be able to read with a multimeter;
3) Fuel pump and fuel pump relay. To check this, remove the IAT sensor in the throttle body transition casting and spray starter fluid into the throttle body. Replace the sensor finger tight and crank the car. If it starts and runs until the starter fluid is gone, you probably have a pump or relay issue. Raise the rear seat and hammer on the top of the tank next to the fuel pump assembly with a large rubber mallet and then try to start the car. If it starts and runs, your pump is probably failing. Check the relay under the dash regardless to ensure that it is working. You should be able to hear the pump run when you turn the key to the on position, especially with the rear seat up.
